SYRINGE.

iniaaei.

T0 all whom it may concern Be it known that I, FREDERICK O. NORTHEY, acitizen of the United States of America, residing at New rleans, in theparish of Orleans and State of Louisiana, have invented certain new anduseful :linprovements in Syringes, of which the 'following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to syringes particularly designed for use inhypodermic injections or for the sub-cutaneous introduction of vaccinesand serums.

It is the object of the invention to obtain a construction in which theneedle as well as the vaccine is held in an antiseptic container.

It is a further object to adapt the device for successive operationswithout contamination of the vneedle in the operations or the waste ofany of the fluid.

With these and other objects in view, the invention consists in theconstruction as hereinafter set forth.

In the drawings,-Figiire 1 is a longitudinal section through the barrelor fluid container in condition for shipment; Fig. 2 is a similar viewshowing the needle and its container; Fig. 3 is a section showing themanner of engaging the needle with the barrel or fluid container; Fig. lis a longitudinal section through the parts in assembled position.

` A is the fluid container preferably formed of a glass cylinder havingat one end the contracted nipple B which is preferably eX- teriorlysecured thereto.

C is a removable stopper for closing the aperture in the nipple B.

D is a plunger within the barrel or cylinder A and which has anoperating stem ,or piston E passing out through a stopper F and rovidedat its outer end with a handle f H is the needle provided with asuitable head or cap portion I interiorly threaded to engage thethreaded nipple 4B.

J is a container for the needle and its cap which is adapted to'completely inclose the same and form an antiseptic package. Thiscontainer is preferably formed also of glass and has a contracted end Kin which is placed a suitable porous substance L for ho ding anantiseptic oil. Any suitable material may be used for holding theantisep- Specification of Letters Patent.

tic, as for instance absorbent cotton, cork, etc. The needle when placedin the container will have its point embedded in the antiseptic holdervLand by reason of the fact that the antiseptic material is an oil theneedle will not rust. The opposite end of the container J is perferablyprovided with a bushing M of cork or other suitable material forsupporting the head or cap I and the container is then closed by asuitable cork N.

With the construction as thus far described during the shipment, thecontainers A and J are separate and each forms a thoroughly antisepticprotection for its contents.

`When the device is to be used the Stoppers C and N are removable andthe cap l while still within the container' J is engaged with thethreaded end of the nipple B and screwed to its seat, preferably `agasket O on the container A. As soon as the needle is in position thecontainer J may be drawn off the same and the device is then incondition for use without the necessity of the operator touching theneedle with his hands or otherwise contaminating the same. After theinjection the needle may be replaced in the container J and the pointwhich has been contaminated by the operation is again sterilized byinsertion in the material L with its antiseptic `fluid. The fluid in thecontainer A which has filled the cap I and the passage through theneedle, is not in any way contaminated and is used in the subsequentoperation without loss.

It will be understood that my improved construction has variousadvantages including first, the saving of the vaccine material which isusually lost when the needle is removed; second, it avoids the necessityof sterilizing the needle after each operation in any other way than byreplacingof the cap or protecting container J thereof; third, it avoidsany danger of contaminating the needle during the operation of engagingthe same with the syringe barrel.

What I claim as my invention is:

1. In a syringe, the combination with a barrel or container' for thefluid to be injected, of a needle attachable to said barrel, anantiseptic container for said needle, sterilizing means Within thecontainer in which the point of the needle is embedded when the latteris positioned within the container,

ing of resilient material detaohably engaging said cap, the latterserving to close the casing, said bushing being arranged to per- 15 Initthe Cap to be secured to the barrel Whilel the needle is inolosed by thecasing.

.In testimony whereof I afx my signature in presence of two Witnesses.

FREDERICK o. NoRTI-IEY.
